What Others Think

Hmm... grep, cut, awk and xargs? I'm sure we can do better. First, let grep do the hard work: ... | grep -o '[^"]*Linux/7/pdf[^"]*' | ... Look for quote delimited string that includes Linux/7/pdf and only print the matching string (-o) Now we don't need cut. As a personal preference, I'd have chosen sed rather than awk for the replacement. But then I realised we didn't need that either. Change xargs to specify the argument ... | xargs -I{} wget{} Finally, replace wget with curl to save a few characters :-) curl -s https://... That leaves: curl -s | grep -o '[^"]*Linux/7/pdf[^"]*' | xargs -I{} wget{}
